There is now suggestive evidence that vitamin C may be essential to the welfare of many systems. Accordingly, an attempt will be made in this report to answer the following five questions:

1. What is the frequency of reported cardiovascular findings in a presumably healthy population?

2. What is the daily ascorbic acid intake in this same group?

3. Is there any relationship between the frequency of reported cardiovascular symptoms and signs and daily vitamin C consumption?

4. What changes in this frequency of reported cardiovascular symptoms and signs occur following a one year experimental aeriod during which group nutritional improvement instruction sessions were conducted?

5. What are the possible significances of these findings?
